Preact, Without Build Tools

This is a demonstration of using Preact without any build tooling. The library is linked from the esm.sh CDN, however a standalone JS file exporting HTM + Preact + Hooks can also be downloaded here.

preact-root-fragment: partial root rendering for Preact

This is a standalone Preact 10+ implementation of the deprecated replaceNode parameter from Preact 10.

It provides a way to render or hydrate a Preact tree using a subset of the children within the parent element passed to render():

<body>
  <div id="root">  ⬅ we pass this to render() as the parent DOM element...

AsyncComponent for preact

This is the guts of preact-cli's import X from 'async!./x' feature, extracted into a standalone library.

It creates a wrapper component that, when rendered, lazy-loads your real component. While loading, any SSR'd DOM is preserved intact.

Option 1: lazy()

This is the API of React.lazy() or preact-iso's lazy(), but it does not use Suspense.

Rendering Interactive HTML using Preact

It's possible to render HTML in Preact using the dangerouslySetInnerHTML prop, however doing so bypasses the Virtual DOM entirely. This may be reasonable for static HTML, but interactivity can be a little painful to graft on without VDOM.

There is another technique available that melds HTML to Virtual DOM without such limitations.

Enter DOMParser
